3 Claims.

This invention relates to awaxing attachment I for spoolers, spinning frames, winders and the 1 like and more especially to what is termed as cake waxing.

It is common practice in mills to pass a strand of yarn in contact with a cake of solidified wax in order that wax might be applied to the periphery of the strand. In many instances the cake vof wax is rotatably mounted around a pin which extends upwardly from a base member. The strand is drawn between the lower surface of the cake and the upper surface of the base member, and While passin therebetween, a coating of wax is applied to the strand. Due to the fact that the temperature runs rather high in mills, there is a tendency for the cake of wax to partially melt and become distorted so that it will not rotate around the pin as the strand is drawn past the lower surface of the cake. This failure of the cake of wax to rotate allows the strand to out 'a groove in the lower portion thereof, after which the yarn will collectvery little wax.

It is, therefore, an object of this invention to provide a waxing attachment comprising a base .member with a fiat upper surface over which the strand is adapted to be drawn and a pin rising from the central portion thereof with an inverted cup member rotatably mounted around said pin. The cup member has a cake of waxing material loosely mounted therein which rests upon the strand and upon the upper side of the base member. This cup member prevents lateral distortion of the cake due to excess heat thereby keeping the bearing area on the lower face of the cake substantially the same at all times. As the strand is drawn beneath the cake member the cake will rotate to deposit wax on all portions of the yarn.

It is a further object of this invention to provide an apparatus of the class described having means disposed in the cup for weighting the top of the cake so that the necessary pressure will be applied by the lower portion of the cake upon the strand. This weighting member also keeps the top surface substantially level, thereby preventing distortion-and causes the cake to feed downwardly as the lower bearing surface is worn ofi.

It is a further object of this invention to provide a waxing attachment of the class described having means for indicatin the thickness of the cake of wax remaining in the cup at all times.

Some of the objects of the invention having been stated, other objects will appear as the description proceeds when taken in connection with the accompanying drawing, in which- Figure 1 is a plan view of an improved waxing attachment shown in conjunction with a tension device and a slub catching device;

Figure 2 is a vertical sectional view taken along the line 22 in Figure l;

Figure 3 is an exploded isometric view of the invention.

Referring more specifically to the drawing, the numeral it denotes a suitable transverse rod of a spooler, winder, spinning frame or the like, upon which is secured a bracket l I. This bracket has 10 an eyelet l2 therein through which a strand of yarn M is adapted to pass. From this eyelet the yarn passes between disks l5, and it, which act as a tension device. The upper disk It is weighted by a suitable washer ll, the number of which may 15-- be varied. depending uponthe amount of tension desired to be exerted upon the yarn. All of the members l5, l8, and H are rotatably mounted around a pin 18, which is anchored in bracket II.

The central portion of the bracket I I has a pin 2.0

It, extending upwardly therefrom around which is rotatabl mounted a member 20. This member ZBhas a base portion 2! and an upwardly extendingcylindrical projection 22, said projection having a hole '23 in the central portion thereof which 25.

is adapted to rotatably fit over the pin IS. The projection 22 of the member 26 is adapted to fit in a cylindrical hole 24 in sleeve 25. The sleeve 25 forms an integral part of a cup member 26. By referring to Figure 2, it will be seen that the lower 30 rim of sleeve 25 normally rests upon base portion 2! and is slightly lower than the rim of the cup 26. This allows the rim of the sleeve 25 to support the cup when it is in an inverted position and also allows the strand of yarn I4 to pass be- 35 neath the rim of the cup member 26 without contacting the same. Disposed within the cup member 23 and around the sleeve 25 is a cake of waxing material 21, such as parafiine and the like. This cake is cylindrical in shape and has a hole 40 28 in the central portion thereof for fitting around the sleeve 2'5.

When the cake 2'! is disposed in the cup 26 in the manner shown in Figure 2, the lower surface thereof normally rests on the top of the base 45 portion 2i of member 2!! thereby binding the strand It therebetween. Due to the fact that the cup member 26 is rotatably mounted around the upstanding projection 22 and since the member 20 is also rotatably mounted around its as- 50 sociated pin l9, it is seen that upon drawing the strand of yarn I4 beneath the wax that a rotary motion will be imparted to the wax cake, thereby causing the lower portion of the wax to be evenly worn by the passing strand. Since the 55 periphery of the cake 2! is held by the sidewalls of the cup member 26, it is impossible for this cake to become laterally distorted any appreciable amount even though it is subjected to relatively high mill temperature.

It has been found necessary in some instances to provide a suitable weighting means on topof the cake of wax 21 and within the cup 26, so that the necessary downward pressure will be exerted upon the cake of wax. Therefore a washer 35 has been provided with a hole 35a therein, said washer being mounted around sleeve 25 and on the top of cake 21. This washer may be of any desired thickness, depending upon the amount of weight desired to be exerted upon the wax. Studs 36 and 31 are secured in opposed sides of the washer, said studs being adapted to penetrate the slots 38 and 39 respectively in the cup 26.

The pins 36 and 31 are visible from the exterior of the cup and thereby furnish means for indicating the amount of wax within the cup. The slots 38 and 39 also serve as a guide for the washer as it moves downwardly. This washer, in addition to furnishing weight to the cake of wax also serves to maintain the top side of the cake substantially level and prevents distortion.

After the strand I4 leaves the waxing attachment, it is adapted to pass beneath a bar 40 and over a plate 4|. Disposed above the plate 4| at a slight distance from the top of the strand I4 is a comb 42, which serves to receive slubs from the strand.

In the drawing and specification there has been set forth a preferred embodiment of the invention 35 and although specific terms are employed, they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being set forth in the appended claims.

I claim:

1. Apparatus for applying wax to a strand, comprising a rotatable disk, means for passing a strand over the upper surface of the disk, an upstanding portion integral with the center of said disk, an annular cake of wax disposed around said upstanding portion and having a substantial clearance between the inner surface of the wax and the upstanding portion, means for passing a strand between the lower surface of the wax cake and the disk member, an inverted cupshaped member disposed over and aroundthe wax for confining the wax and retaining the wax in its annular condition, and an annular member disposed within the cup and resting on the upper surface of the cake of wax for pressing the wax into contact with the strand.
